Problems solved by technology
[0002] In the underground mine filling process, the ground filling is built on the surface, and the filling equipment, mixing process and the preparation of the entire filling are relatively advanced and transparent. However, when the filling material enters the stope, the stope is relatively closed, and personnel and equipment cannot enter during the filling process. , and there is no detection and control of the filling process. Since the filling process is fully closed, it is impossible to have an objective understanding of the filling process, and there is no way to evaluate the overall force status of the filling body.

The invention relates to a mine stope filling body simulation experiment device and method. The device comprises a bottom plate, the bottom plate is provided with an experiment box body for filling asimulation material, and the front and rear side walls of the experiment box body are respectively formed by the splicing of a plurality of detachable transparent tempered glass plates; a plurality ofupper pressing plates in one-to-one correspondence with the tempered glass plates on the front side wall and the rear side wall are arranged on the upper side of the experiment box body, and side pressing plates are arranged on the inner sides of the left side wall plate and the right side wall plate of the experiment box body respectively. The mine stope filling body simulation experiment deviceis convenient to use; easy operation, practicality, the stope excavation and filling processes and the stress conditions of the top and the filling body in the process can be simulated and analyzed;compared with the prior art, the real mining process is greatly restored, a basis is provided for improvement of a supporting and filling process adopted on site, workers can visually know the real mining and filling process, and the problem that the stability of a stope and a filling body is difficult to detect under the deep operation condition of a metal mine is solved.
Description
technical field [0001] The invention relates to a simulation experiment device and method for a filling body in a mine stope. Background technique [0002] In the underground mine filling process, the ground filling is built on the surface, and the filling equipment, mixing process and the preparation of the entire filling are relatively advanced and transparent. However, when the filling material enters the stope, the stope is relatively closed, and personnel and equipment cannot enter during the filling process. , and there is no detection and control of the filling process. Since the filling process is fully closed, it is impossible to have an objective understanding of the filling process, and there is no way to evaluate the overall force status of the filling body. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a kind of easy to use, highly practical mine stope filling body simulation experiment device and method...
